INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a liquid crystal display and a liquid crystal circuit, and particularly relates to a bilateral moving liquid crystal display and a prior art liquid crystal display thereof. The screen size is getting healed: :: "," to send out the drive signal, so that the drive nickname does not cause delay due to the large size of the liquid crystal display. However, any drive signal output from the drive chip at one end occurs. The error 'ground is located, the driver should be driven," and the line defect is formed. The solution to the problem is: when the line defect problem is found, the screen of the line defect is moved to the laser repairer, and the control line for the occurrence of the line defect is cut off by the laser. This method takes a lot of time and Manpower, 'Before the control line that isolates the problem with the laser repairer, it needs to be supplemented.” Where the line defect occurs, the control line can be cut off. , the need for more: force to complete the removal of all control lines that occur line defects. [Summary of the invention] In view of this panel driver circuit 1262469 V. Description of the invention (2) when the control signal is spent, in addition, the present invention i dim: for the purpose; to reduce the manufacturing cost. The display panel drive circuit, the mouth: use the above liquid crystal to achieve the above objectives, the hair is used to increase production capacity. Road, at least including · 唆 " road type LCD Display panel drive electric number electrode; =: end: idler driver, respectively, wheel; pole; where, the first, second = up to the pulse signal to the gate of the pulse signal is positive::.At With automatic When the detection itself is correct, it stops: when the measurement of a certain - clock signal is not based on the pulse signal. Add a detection device, ! I station, shame in the output of the gate driver is Λ 2, the detection device has the function of detecting the pulse signal to be outputted. If the result of the debt measurement is yes, the detection device outputs the pulse signal $11 to the "electrode.signal". If the test result is no, it means that the pulse signal is a wrong signal, and the pulse detection device does not output the pulse signal. By enabling the gate driver to automatically detect the pulse signal k2 outputted by itself, the correctness of the pulse signal can be known in advance, so that the wrong pulse signal can be detected early, and the line generated by the conventional can be improved.
